What should be similarities among homologies?
Homologise have the different molecular masses so can not have the same physical properties, due to same functional group they show same chemical properties but with different rates of reaction.
What are homologies and why are they important in classification?
Homologies have similar characteristics due to being related. You are able to see homologies by comparing the anatomies of different living things, look at the cellular similarities and differences, look at the embryological development and compare and look at vestigial strutures. Even though leaves of plants look different and have different shapes and functions, they are homologous because they share a common ancestor.
What are the 4 traditional methods to classify organisms?
Whereas previously classification was based on homologies, that is the shared characteristics from common ancestors, modern classification is based on the following four methods:symmetrymorphologygerm layersembryonic development
What are some homologies at the cellular level?
There are many similarities on the cellular level between organisms, plants and animals alike. For example, both cell structures contain membrane, ribosomes and mitochondria as well as a nucleus and nucleolus to control cell functions.
Relationship of chemical formula chemical reaction and chemical equation?
Chemical formula is representative for the chemical compositon of a compound. Chemical equation is representative (describe) for a chemical reaction.
What is the definition for homologous?
anatomical homologies
What are the different types of homologies?
Alakane and Alkene

How does genetics help in the study of evolution?
Genetics allows us to chemically study the evolutionary history of organisms in a way that cannot be disputed. You cannot argue against basic chemical signiture homologies.
How are chemical homologies useful in classification?
The more similar (or homologous) some chemical structures are, the more likely they are closely related. Conversely, greatly dissimilar structures indicate divergence a long time ago. If the only other clues about an organism are not specific enough, the chemical structures - and thereby other organisms - it is related to can be discerned by such a comparison.

What is the definition for Anatomical Homologies?
The definition of developmental homologies is something that can be viewed in the fossils of certain animals that point to and evolutionary change in their current incarnations. For example snake fossils when compared to current snake skeletons show that the ancient relatives of snakes actually had feet and over time they feet pulled closer into their body eventually developing into the snakes of current times.
What has the author Holmes Coote written?
Holmes Coote has written: 'The homologies of the human skeleton ..'
What is developmental homologies?
Developmental homology is recognized in embryos. Two different organisms can have a common embryonic trait, say gill pouches or a tail, but in some of those organisms those gills and tails are lost. Gills pouches and tails are vestigial traits in humans, cats, chickens, etc. These organisms share genetic homologies, but are structurally different.
What is a homologies?
This are chromosomes that have exactly the same length that contain the same gene but those genes have different alleles.
What are five types of homologies that provide evidence of common ancestry?
limbs wings legs arms and flippers
What is meaning of morphology?
That branch of biology which deals with the structure of animals and plants, treating of the forms of organs and describing their varieties, homologies, and metamorphoses. See Tectology, and Promorphology.
